Coding Convention and IDE Customization
There is always a huge discussion about how to "format" one's code. Since it's mostly personal preferance issue, I don't care too much about how other people do.
I absolutely love my darn stupidity. :) So I had to use the multiply blend op this week at work to implement some kinda per-geometry glow effect that our FE artist mocked up in Photoshop. Unfortunately, he didn't have the PSD file around anymore, so I had to believe what he said: it is using a additive blend layer in Photoshop + outer glow.
Probably it's same for a lot of people out there. I always have a lot of chores to do by certain date and I always wanted to have a good program which keeps track of my task list with deadline. Also it should notify me a daily or weekly summary, preferably via email.
